Hi all. I've owned a BSA A10 1952 plunger since 2014. My father gave me the bike a few months before he passed away in 2015 (1926-2015 RIP dad). He only ever owned British bikes and had owned over 60 bikes during his riding career. Our main form of transport as a family was a Bedford CA and several sidecar outfits, including Norton ES2 and Panther Model 100. He bought this A10 in 2005 and used it mainly with a sidecar, which is why he wanted a plunger frame, I believe.
As for myself, I ride a BMW RnineT mainly for summer commuting to work.
